"Many of us know it: cold feet in the evening that prevent you from falling asleep, or a tropical summer night that comes with restless sleep. The fact that body temperature and sleep are inseparably linked, is also evident from a scientific perspective. The right temperature at the right time is essential for good sleep. Dagsmejan’s sleepwear can support the nightly changes in body temperature and thereby naturally improve sleep."

Great purchase!

Got these for my husband who is always cold. He absolutely loves them! He’s tall at 6’3” and has trouble finding pajama bottoms that are long enough, but the XXL size work really well even with his slender frame.
